Introduction: Why I’ve Faced This Question Myself

If you’re looking at a list from your dentist that makes your mouth look like it has way too many problems—lots of teeth needing fillings—you’ve probably thought, “Can my dentist just fix all these in one go?” I get it, because I’ve wondered the same thing. Nobody likes planning lots of trips to the dentist, and if sitting in the dental chair makes you nervous, it’s even more tempting to get it over and done with at once.

After many years of going to the dentist (believe me, I’ve had plenty of fillings), I’ve learned a lot about what it’s like to get more than one cavity fixed during the same appointment. Let me tell you what I’ve found out, from helpful advice to some honest truths your dentist might not always explain right away.

The Short Answer: Yes, But Let Me Explain

Let’s not waste time. Yes, dentists can and often do fill more than one cavity during a single visit. In fact, most general dentists are used to doing two or three fillings at once, sometimes even more, especially if the teeth needing help are next to each other.

But, and this is important: it’s not always the same for everyone. There’s a bunch of things that decide if it makes sense to do all your fillings at once. Sometimes, the answer is “for sure!” Other times, your dentist may say it’s better to spread them out, and there’s good reasons for that.

What Decides If You Can Get Multiple Fillings at Once?

From what I’ve seen, dentists look at a few things before they sign you up for a longer appointment. Here’s what they think about and why it matters for you.

Number and Location of Cavities

If you have two or three cavities in the same area of your mouth—like a few molars grouped together—it’s much easier for your dentist to numb that whole spot and work efficiently. I once had three upper right molars filled in one go, and it all went super fast.

But if your cavities are spread out—one on top, one on the bottom, and another across your mouth—it gets tougher. The dentist has to be careful with how much numbing medicine they give and how many different places to numb at once.

Size and Depth of Cavities

Not every cavity is the same. Small ones, if caught early, can be filled quick. But a deep or tricky cavity? That takes more time. Once, I had a really deep filling and my dentist took extra care to avoid hitting the nerve. Bigger or more difficult cavities might take longer, or could even need a root canal, which makes it harder to do a lot at once.

Type of Filling Material

I didn’t know until a few years back that white (composite) fillings need more time. Dentists have to put them in layer by layer and shine a blue light on each layer to make it harden. Silver (amalgam) fillings can go in faster.

So if you’re getting all white fillings on your front teeth or your back teeth, plan for more time in the chair. But the good thing is, your teeth will look great.

Patient Comfort and Your Tolerance

Everyone handles dental work differently. I have friends who almost nap in the chair, and others (me sometimes) who start getting antsy after twenty minutes.

How long you can keep your mouth open, how many spots can be numbed at one time, and how your jaw feels all matter. For longer appointments, I now always ask for a little mouth prop—it really helps my jaw feel less sore.

Dentist’s Preferences and Scheduling Realities

Every dentist has their own way of doing things. Some are good with booking you for long visits and working quickly, others like to spread out appointments. If their schedule is packed, or if they think the treatment might take too long, they’ll likely suggest splitting the work up. That’s happened to me, especially when the office is super busy.

Anesthesia and Sedation Options

Getting numb is great, but there’s a limit to how much numbing medicine you can get. If you need more than one area numbed, your dentist has to pay attention to how much they use. For longer visits, some dentists have laughing gas or give you pills to help you relax. One time, I tried nitrous oxide (laughing gas), and it made the long dental appointment fly by.

Just know—not every dentist’s office has all the gear for deeper sedation. If you want that, always ask ahead.

A Step-by-Step Look: My Experience Getting Multiple Fillings

If you’re new to having more than one filling in a day, here’s how it went for me. Knowing what to expect made me much less nervous.

Before the Appointment: Preparing

On the day, my dentist took fresh X-rays to see all the bad spots, checked how deep the cavities went, and told me which teeth he’d fix, what kind of fillings he’d use, and how long I’d be there. I made sure to eat well before going. You don’t want to be hungry when your mouth is numb!

During the Appointment: What Actually Happens

If your jaw starts to get tired, don’t feel bad about asking for a short break. I’ve had to do that before!

After the Appointment: Recovery and Aftercare

When I leave the dentist, my mouth always feels very numb—for up to three hours! Don’t drink anything hot or try to chew big bites right away. You could bite your cheek or tongue without feeling it.

After getting a few fillings at once, your teeth might feel sensitive when you bite down or have a cold drink. That’s normal and usually goes away in a week or two. If it doesn’t, just call your dentist.

The Benefits I’ve Noticed with Multiple Fillings in One Visit

Here’s why fixing more than one cavity at a time works for me:

• Saves Time: Less appointments. I don’t have to keep coming back!
• Less Numbing: Get numb once, take care of many teeth. Fewer shots always makes me happy.
• Less Worry: For me, it’s easier to face one longer visit than thinking about lots of short ones.
• Might Cost Less: Sometimes, doing more in one visit means fewer extra charges (ask your insurance).
• Stop Cavities Fast: My dentist says getting all the work done helps stop small problems before they get worse (like needing a root canal or crown).

Honestly, finishing all the fillings at once just feels good—like getting a big chore out of the way.

What to Watch Out For: Drawbacks and Considerations

But it’s not perfect. Getting a bunch of teeth fixed at once can be a little tough:

• Longer Sitting: My longest time was 2.5 hours! Bring some patience.
• Jaw Ache: The longer your mouth is open, the more it can hurt. Remember to ask for a break.
• Feeling More Numb: You might feel like half your face is frozen. Not a great time for calls or eating out.
• Sensitivity: Sometimes, after getting a few teeth fixed, you’ll notice cold or heat bothers those teeth. It goes away most of the time.
• Numbing Limits: If you need a lot done in different places, there’s only so much numbing medicine you can get safely.
• Healing: Sometimes, one or two teeth stay sore for a few weeks after a big visit.

None of these were super bad for me, but it’s good to know before you do a long appointment.

Tips I Wish I’d Known Before My First Multi-Filling Session

Really—your dentist wants you to be okay. They would rather you be comfortable than trying to tough it out.

When It’s Not the Best Idea (and When My Dentist Said No)

There have been times where my dentist said it was better to split up the work. Here’s when that usually happens:

• Very Deep Cavities: If a filling is close to the nerve or might need a root canal, it’s better to take more time on that tooth.
• Extra Nervous: Some people need more than just laughing gas or can’t sit through long appointments.
• Health Issues: If you have a health problem or heart condition, it’s safer to do less at once.
• Jaw or Gag Problems: If your jaw gets sore quick, or you gag a lot, shorter visits are better.
• Too Much Anesthetic Needed: Your dentist is careful about how much numbing medicine you get at a time.

The main thing: talk honestly with your dentist about how you feel and what you can handle.

My Closing Thoughts: Working With Your Dentist for the Best Results

What I’ve learned is that every person is different. Sometimes, fixing all your cavities in one trip is easy and saves time. Other times, breaking it up makes more sense.

The best thing is to talk openly with your dentist. Ask about your options, what to expect after, how long it will take, and what kind of numbing or sedating they can do for you. Tell them your worries. Good dental care is about more than just teeth—it’s about you, too.

Frequently Asked Questions

Can every dentist fill multiple cavities at once?

Most regular dentists can, but it depends on the dentist, tools, and what your teeth need. Really tricky cases may need more visits or a special dentist.

How many cavities is it safe to fill at a time?

Usually, 2–4 cavities (if they’re close together) can be done at once. More than that depends on if you’re comfortable, how tricky the fillings are, and how much numbing is safe.

What happens if you have lots of cavities at once?

Don’t freak out. Your dentist will usually make a plan to fix the most urgent spots first, then finish the rest as soon as possible.

Will my insurance cover multiple fillings in one day?

Most times, yes. Insurance pays for the treatment, not how many visits you have, but check your plan for details about payments.

Are there different types of fillings for multiple cavities?

Yes! Your dentist will choose what works best for each tooth and for how it looks. For more details on materials, see [dental ceramics lab] or [digital dental lab].
